JL Audio M6-10IB Luxe: 10-inch marine subwoofer
The M6-10IB Luxe is the 10-inch marine subwoofer in the JL Audio M6 series. IB stands for infinite baffle: it is made to play with no dedicated enclosure, yet it can also be used in a box. It handles 250 W RMS continuously into 4 ohms.
The Luxe grille, low in profile and larger in diameter, comes in two finishes: Gloss White and Satin Black.
Key features
- 10-inch subwoofer, 4 ohm nominal impedance
- 250 W RMS continuous power

Bass
The woofer is optimised with DMA, the proprietary JL Audio technology that acts on the motor, the suspension and the cone profile to lower distortion, improve transient response and deliver clean, well controlled bass. The result is bass that stands out for cleanness, and just as much for smoothness, balance and precision. The M6 series is made to benefit from a quality amplifier.
Parameters
For system designers: free-air resonance 43.76 Hz, Qts 0.840, Vas 27.75 litres, linear excursion Xmax 13 mm, effective piston area 0.0323 square metres, DC resistance 4.543 ohms. Stated sensitivity is 86.1 dB with 1 W at 1 metre.
Reference volumes
Manufacturer data for anyone who prefers a box: sealed, 56.6 litres net with a -3 dB point at 41.54 Hz; ported, 70.8 litres net, tuned to 30 Hz with a -3 dB point at 25.09 Hz. The stated wall thickness is 19 mm.
Luxe grille
The Luxe grille is a mesh type and wider than the Classic and Sport ones: it is 319 mm in diameter against 273 mm and stands only 14 mm proud of the mounting surface. It therefore needs a different cutout, 268 mm instead of 225 mm: a measurement to check before cutting.
Installation
Outer diameter is 319 mm and the cutout measures 268 mm. Weight is 6.0 kg. The grille stands 14 mm proud of the panel, the fixing holes lie on a 291 mm circle and the driver displaces 2.80 litres. The grille comes off with the supplied tool. Terminals are fork type. Like the rest of the series, this model is made to live at sea and to cope with salt water in the long run.
